[QUOTE="TheBullLady, post: 573122, member: 173"] Hmm.. I have to disagree. My experience with Johne's cows has been that they DO go off their feed for periods of time. And two years old is not unheard of, although generally it's found in older cows. I have noticed, and research has suggested, that after a stressful event, ie: calving, or weaning a calf, that's when you'll start seeing symptoms. It's not uncommon for a Johnes infected cow to "get better", possibly even enough to get bred back, and calf again. However, she will no doubt get symptomatic again, and possibly worse the next case. It's a good idea to test her. It's good that she's not out of any of your herd, so you don't run as much risk of a sibling having it. But if she is positive, you'll have to watch everything in the herd for a year or so. [/QUOTE]
